Blackpool could look to this market as they aim to improve their squad throughout Steve Bruce’s first pre-season at Bloomfield Road – following his appointment back in September.
The Seasiders have already been linked with a number of free agents in the last few weeks, while they continue their own talks to keep both Sonny Carey and Matthew Pennington on the Fylde Coast beyond their current deals.
